| Abstract: | The function and characteristics of FCC feeding nozzle are reviewed,the structure characteristics,atomization mechanism and atomization effect of different types of feeding nozzles such as pipes,target,bubble atomization kind,swirling kind,three times of atomization,pneumatic spray and spray with bubbles are introduced.The development direction of feeding nozzle is to look into the gas-liquid phase flow theory and gas-liquid initial function,as well as the uniformity of spray field.The feeding nozzle types need to further research to make the atomization particle size appropriate and pressure drop distribution reasonable. |
